SPECIFICATION forming part of Letters Patent No. 319,553, dated June 9, 1885. Application filed October 13,1884. (No model.)

To all whom it may concern,.-

Be it known that we,IsAAc Bnoirnw and WESLEY BUTLER, of Litcheld, in the county of Montgomery and State of Illinois, have invented a certain new and useful Improvement in Straw-Stackers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a side elevation of the stacker mounted on a trucl Fig. 2 is a transverse section taken on line 2 2, Fig. 1, looking toward the truck. Fig. 3 is an enlarged detail longitudinal section of the adjusting-tubes. Fig. 4 is an elevation viewed from the machine end of the apparatus. Fig. 5 is a plan view, the elevating-frame being omitted. Fig. 6 is a top view with the elevating-frame in place. Fig. 7 is atransverse vertical section taken on line 7 7, Fig. 5. Figs. 8 and 10 are detail sections in plan taken on line 8 10, Fig. 7, showing the parts in different positions. Fig. 9 is a detail vertical section taken on line 9 9, Fig. 8. Fig. 11 is a similar view taken on line 1111, Fig. 10. Figs. 12 and 13 are enlarged detail views, more particularly referred to hereinafter. Fig. 14 is a vertical section on the line 14 14, Fig. 7.

Our invention relates to a straw-stacker, which may be connected to the thrashing-ina chine, or may be mounted on a truck, as shown.

Our invention consists in features of novelty, hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents the elevator-frame made in two parts, A A2, to which are secured ytubes A3 A4, those A4 telescoping those A3, or vice versa, and being ad- 40 justed in and out, to lengthen and shorten the frame, by sprocket or rag wheels B, engaging perforations A5 in the tubes A4 A4, (see Fig. 3,) and being secured to a shaft, B', j ournaled in boxes B2, made fast to the part A of the frame. (See Figs. 1 and 2.) The shaft B is turned to shorten or lengthen the frame by means of a shaft, B3, connected to the shaft B' by miterwheels B, and having a crank, B5, by which it can be turned. This shaft is journaled in boxes B, secured to the part A of the frame.

AG represents clips connecting the two parts of the frame.

Vhen the machine is at work, the frame is lengthencd out, as shown in Fig. 1, and when the machine is being transported from place to place the frame is shortened up, as shown by dotted lines, Fig. 1, when the raddle will be received by a box, Bl, secured to the truck. (See Fig. 1.)

rlhe raddle C consists of an apron, of fabric or other suitable material, and cross-slats C. The raddle thus consisting of a belt or apron, the chaff, &c., cannot fall through it, but is carried up and discharged over the end ofthe frame. It passes around rollers C2 G3, journaled in the outer and inner ends of the frame, respectively, and is driven by a belt or chain,

C", passing round a pulley or wheel, C5, on

one end of the shaft or roller C3, and around a pulley or wheel, OG, on a shaft, G7, journaled in boxes secured to standards G of a bolster, C, supported by a toggle frame, D. This shaft G7 has another pulley or wheel, C, that is connected by means of belt or chain G1 with a pulley or wheel, C, on a shaft, C, supported by and extending halfway across the bolster, and having on its inner end amiter-wheel, C, meshing into a similar wheel, C, on the upper end of a vertical shaft, C15, which pivots the bolster to the toggle-frame. On the shaft G15, beneath the bolster, is a miter-wheel, G1, engagedby a miter-wheel, C", 0u the inner end of a shaft, C18, journaled in boxes C1, secured to the toggle-frame. 0n the outer end of this shaft C is apulley or wheel, C20, connected by means of a belt or chain, O21, with a pulley, U, on one end of adrivingshaft, C, journaled to the truck, (see Figs. 1, 4, and 6,) and provided with a driving-pulley, C, that receives power from the machine or elsewhere, and thus the raddle is driven. 'The elevator-frame is hinged to the standards C9 of the bolster GB by the shaft C7, which passes through strips C3", secured to the section A of the elevator-frame. The rear end of the elevater-frame is held down to support its outer end by ahanger, G25, having a friction-roller, O2". that engages beneath a circular rail, 0'", secured to the toggle-frame, and it will thus be seen that the outer end of the elevatorframe will have free lateral movement, the bolster turning on the shaft C15, and the wheel or roller C2. turning beneath the rail. The hanger C is strengthened by brace-rods G25.

IOO

The elevator-frame is raised and lowered by the toggle-frame as follows: This frame consists of a vertical part, D', inclined parts D2 D2, and strips D2, connecting the inclined parts. The inclined parts are pivoted at the upper ends to the vertical part at D5, and the lower end of the part D2 is hinged to standards D, secured to the truck, (see Fig. 1,) while the lower end of the part D3 is connected to the truck by means of pins D', fitting in slots Ds of plates D2, bolted or otherwise secured to the truck. (SeeFig. 1.) The side pieces orstrips, D4, are connected to the part D3 by bolts D2",y fitting in slots D11 in the side pieces. It will now be seen that by pulling the lower end of the part D3 the elevator-frame will -be raised, and it will also be seen that the outer end of the frame will be raised a much greater distance because ofthe track or rail G22 (to which the inner end of the frame is made fast by the hanger, as specified) being made fast to the side pieces,D",which are connected to the part D2 midway between its upper and lower ends. The bolster and vertical part of the toggleframe is of course raised as the lower end of the part D3 is pulled inward. As a means for pulling the lower end of the part D3 inward We have shown ropes or chains H, connected thereto, and to a drum, H', or two rollers secured to a shaft, as shown in Fig. 5, journaled in boxes secured to thelower end of the part D2. The roller or shaft has a cog-wheel, H2, engaged by a worm, H3, provided with a crank, H2. It is journaled in boxes H", secured to cross-pieces H,ma`de fast to the part D2 above the wheel H2. The ropes or chains H pass under friction-rollers D20 on the lower part of the vertical member of the toggle frame. (See Figs. 4 and 7.) At D31 are shown radiusrods which are parallel with the toggle-bars D2, and which act in conjunction with said bars to keep the vertical toggle-frame D in a vertical position, and at the same time admitting the vertical movement of said frame D'.

As the crank is turned the ropes or chainsl are wound upon the drum and the elevator-frame raised and lowered, as described.

We will now describe our improved device for giving to the elevator-frame a continual lateral-vibration while the machine is at work. Surrounding the vertical shaft G15 where it passes through the bolster G2, and extending a little below the bolster, is a sleeve, I, (see Figs. 5, 7, and 14,) on which, beneath the bolster, is a cogged segment, J, and collars L L',

having cams or projections L2 L2, made adj ustable by screws L4, passing through the collars and jamming against the sleeve. The sleeve,

segment, and bolster are all connected, the 'segment to the bolster by bolts I', (see Fig. 14,)

Meshing into the segso as to turn together. ment is a pinion, N', on the upper end of a vertical shaft, N, (sce Fig. 7,) journaled in boxes secured tothe vertical part of the toggie-frame, On the lower part of this shaft is a cog-wheel, N2, engaged alternately by right and left worms, O' 02, on a sleeve, O, which I frame.

y is loose upon the shaft C22, but which is made the worms, as described, by means of a rockzshaft, P, with cogs P P2, (see Figs. 7, 9, and

11,) provided with a crank, P2, connected by a pitman or rod, T, to a crank, T', of a shaft, T2, journaled in boxes T2, secured to a crosspiece, T5, on the vertical part of the toggle- When the elevator-frame has been swung to its limit in'one direction, one of the cams, L2 or L2, as the case may be, comes against a projection', U', on a vertical rockshaft, U, j ournaled in the vertical part of the toggle-frame, turning it, and through means of a lever, U2, connecting-rod V', and arm V,

with projections V2, (see Figs. 10, 12, and 13,)

' turn the shaft T2, and through it the shaft P,

changing the worms, as described. The arm V is pivoted to the cross-piece T, and the projections, as the arm is moved, come alternately against a crank, T6, on the shaft T2 to rock the shaft. The crank T of the shaft T2 fits in a slot, T2, of the pitman T to allow a spring, W, to pull the shaft T2 quickly in either direction as soon as the pitman moves the crank T' over the dead-center. The spring Wis connected to a crank, T2, on the shaft T2 and to the cross-piece T5, and simply pulls vthe shaft either way after the pitman has fmoved it, as described. The wheelv N2 may be raised out of contact with the worms by a clutch, X, and lever X', (see Fig. 11,) and when this is doneth'e elevator-frame will not have this lateral vibration.
